Project description

Bitcoin secp256k1 C library wrapped with CFFI to use with Python2 and PyPy2.


These results are achieved on an Intel Core i5-4200U CPU @ 1.6GHz:

cffi took: 0.75secs / 74μs per op  / 13391 signs per sec

cffi took: 1.09secs / 109μs per op  / 9170 recovers per sec


This library offers sign, recover and verify from the secp256k1 bitcoin lib used like this:

sig = ecdsa_sign_raw(msg32, seckey)

pubkey = ecdsa_recover_raw(msg32, sig)

ecdsa_verify_raw(msg32, sig, pubkey)
